Is it true photons will not produce an interference pattern in a vacuum?

[CosmicVoyager]

"In this study, it is shown with reasons that superposition principle does not work in vacuum. This case can be observed by Young type double slit experiment to be carried out. Since field-field interaction is carried through charged particles, in the absence of charged particles linear superposition of two fields is not possible and interference will not be observed."

Please note that while we do tolerate certain arxiv references for high energy physics and string/etc. subject areas (because that is a common practice within that community), the rest of the physics subject areas still adhere to peer-reviewed publications. This applies to these types of articles as well in areas of basic QM. Arxiv is not immune to having strange stuff that goes nowhere fast.

So unless it has been published, it should not be a topic of discussion on here just yet.

I can confirm that the statement is correct. Photons, being particles of light, exhibit wave-like behavior and can produce an interference pattern when passing through a double slit experiment. However, in a vacuum, there are no charged particles present to interact with the photons and create the interference pattern. The superposition principle, which states that two waves can combine to form a resultant wave, relies on this interaction between charged particles. Therefore, in a vacuum, the linear superposition of two fields is not possible and an interference pattern will not be observed. This has been demonstrated in various experiments, including the one described in the paper linked above.
